feature request - readOnly attribute for form fields

Hi developers,

I firstly thank you for Sencha 2.0 - great work,
My question is, is some simple way to have readOnly form field?

There is only disabled property which dimms the fields, but I want to only show data to user without changing visual appereance, colors don't change (for. ex. if you view iPhone contacts detail form, you see contact data not dimmed - they are read only). This is normal in ExtJS, but missing in Sencha Touch, but maybe it should be standard attribute.
